Application May 29, 1956, Serial No. 588,161 2 Claims. (Cl. 57-35) This invention relates to improvements in coring of wire rope.

The principal object of this invention is to provide a device for inserting a core in a wire rope from which the previous core has been removed.

A further object is to produce a device of this character which is economical to manufacture and one which may be readily transported from job to job.

Other objects and advantages of this invention will be apparent during the course of the following description.

In the accompanying drawings forming a. part of this specification and in which like numbers are employed to designate like parts throughout the same,

Fig. l is a top plan view of our invention.

Fig. 2 is a cross sectional view taken on the line 2-2 of Fig. l; and

Fig. 3 is an enlarged fragmentary detailed view taken on the line 33 of Fig. 1.

It is a well known fact that the core of wire rope often becomes crushed due to the passing over relatively small pulleys, and particularly under heavy loads.

This tends to flatten the ropeand to interfere with the next coil being wound upon the drum.

It has been found that by removing the core from such rope and inserting a new core, that a good deal of added life is given the rope, as pointed out in applicants pending application Serial No. 527,066, filed August 8, 1955.

The present invention is to provide a means for leading the core into the wire rope in a continuous manner and without the core becoming kinked or whipping due to the natural curvature of new cores.

In the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 5 designates a base plate having flared end pieces 6 and 7. Mounted in the plate 5 there are a pair of pins as shown at 8 and 9, each pin being surrounded by a case-hardened bushing as shown at 11 and 12 respectively.

By viewing Fig. 3, it will be noted that extending through the plate 5 is an opening 13, while a similar opening extends through the plate 5 but in an opposite direction so as to have its upper end to the right of the bushing 12.

2,794,313 Patented June 4, 1957 The upper end of the bore 13 as shown in Fig. 3 is to the left of the bushing 11.

In the flared ends we have placed openings as shown at 14 and 16, the purpose of which will be later seen.

Assuming now that it is desired to place a new core in a wire rope designated at A, it is first necessary to twist the wire rope so as to open the strands and place the same over one of the bushings, for instance the bushing 12 in Fig. 1. We will assume that the old core has been removed and that we are merely inserting a new core.

In order to do this, a new core, shown at B, is inserted through the opening 14 and then passed diagonally under the plate 5 and upwardly through the bore 13 adjacent the pin 9, the end of the core being inserted between the strands just in advance of the pin 9. From then on it is necessary only to pull the rope A toward the right of the drawing, with the result that the new core will be fed into the wire rope to take the place of the former core.

It will also be noted that due to the distance between the opening 14 and the opening 13 adjacent the pin 9, there is suflicient distance for the core to assume a gentle curve and to take its proper lay in the rope with no tendency to kink or whip as it does when the core is uncontrolled. Thus is eliminated a great deal of effort on the part of the workmen in controlling the movement of the core into the rope.

If desired, two ropes may be cored at the same time by utilizing both pins simultaneously, or one rope may be decored and one recored.

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, we claim:

1. A device of the character described comprising a supported plate, means for supporting said plate in elevated position, a pin secured in said plate, a bushing rotatably mounted on said pin, said plate having an opening formed therethrough and angularly disposed at a point adjacent said pin, an opening formed in said support at a point remote from said first mentioned opening and out of alignment therewith whereby a rope core passing through said second mentioned opening will traverse the area beneath said plate in a diagonal direction and into said first mentioned opening to be angularly positioned adjacent said pin and at a point above said plate.

2. A device of the character described comprising a plate having a pair of spaced upstanding pins mounted therein, a pair of diverging supports for said plate, each of said supports having an opening therethrough out of alignment with said pins, and an angularly disposed opening in said plate adjacent each of said pins, said angularly disposed openings extending from the top to the bottom of said plate.
